6 dial clocks issue

[mk3 vinny]

yesterday was driving and when I hit a pot hole the rev counter, volt meter, temp and oil preasuer gauges would bounce, then after about 10 times of this happening they all went off so I thought it would just be faulty clocks so today I replaced them with the spair set I have and the same problem happend after about 10 mins but this time the rev counter was the only one that stoped working at the end

has anyone came across this problem before and how can I sort it as now I have 2 broken sets of clock in 2 dasys

HELP THIS CAR IS GOING TO BE THE END OF ME

[brainsnova]

Printed circuit board, its the plastic part on the back of the clocks
